[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0028] like Figure 1-5 As shown, a children's song singing ability assessment device includes a frame 1, a piano key assembly 2 movably disposed within the frame 1, a flexible array pressure sensor disposed below the piano key assembly 2, a controller 3 and a voice recognition device 4 mounted above the frame 1, and the controller 3 being electrically connected to the voice recognition device 4 and the flexible array pressure sensor respectively.
[0029] Among them, the piano key assembly 2, the flexible array pressure sensor and the controller 3 work together to evaluate the relevant abilities of piano accompaniment skills in children's song singing ability.
[0030] The speech recognizer 4 and the controller 3 work together to evaluate the singing skills related to children's song singing ability. When the singer forgets the lyrics, the speech recognizer 4 and the controller 3 will detect it and conduct the corresponding evaluation.
[0031] Among them, the voice recognition device 4 is made using the ASR-PRO series voice recognition board.
[0032] Specifically, a first limiting plate 11 is installed on the front side of the frame 1, a rotating shaft 12 is installed inside the rear of the frame 1, a hanging plate 13 is installed below the rotating shaft 12, a plurality of springs are hung on the hanging plate 13, a second limiting plate 14 is installed at the upper middle position of the frame 1, the piano key assembly 2 is rotatably connected to the rotating shaft 12, and the rear end of the piano key assembly 2 is hung on the hanging plate 13 by the springs. The piano key assembly 2 corresponds to the first limiting plate 11 and the second limiting plate 14 respectively.
[0033] Specifically, a shim is also placed on the pivot 12, and multiple shims are provided, with each shim located between every two adjacent keys in the piano key assembly 2.
[0034] The spacer serves to reduce the mutual interference between adjacent buttons.
[0035] Specifically, the piano key assembly 2 includes white keys 21 and black keys 22. A limiting block 211 is provided at the lower front end of the white key 21, and the limiting block 211 corresponds to the first limiting plate 11. A first pressure rod 212 is installed at the lower middle part of the white key 21, and a second pressure rod 221 is installed at the lower middle part of the black key 22. A rotating hole 23 is provided on the side wall of both the white key 21 and the black key 22, and the rotating hole 23 corresponds to the rotating shaft 12. The rear ends of both the white key 21 and the black key 22 are connected together with a spring on the hanging plate 13 by a hook 24. The top middle part of both the white key 21 and the black key 22 abuts against the lower part of the second limiting plate 14. The first pressure rod 212 and the second pressure rod 221 both correspond to the flexible array pressure sensor.
[0036] Specifically, flexible pads are installed at the lower ends of both the first pressure rod 212 and the second pressure rod 221.
[0037] The flexible pad is used to protect the flexible array pressure sensor.
[0038] Specifically, a switch button 5 and a power supply 6 are also installed on the frame 1. The switch button 5 is electrically connected to the controller 3, and the power supply 6 provides power to the controller 3, the flexible array pressure sensor, and the voice recognition device 4.
[0039] Among them, the switch button 5 and the controller 3 work together to evaluate the duration of the singer's performance.
[0040] Specifically, lifting components 7 are symmetrically installed at the left and right ends of the frame 1. The lifting components 7 include support blocks 71, which are installed on the frame 1. A threaded hole is opened in the middle of the support block 71, and a screw 72 is threadedly connected to the threaded hole of the support block 71. A pad is installed at the lower end of the screw 72.
[0041] In practice, since the piano key assembly 2 is not connected to a sound-producing device, the singer cannot confirm whether they have pressed the correct key. Therefore, lifting components 7 are set at both ends of the frame 1 to raise the height of the frame 1. A roll-up piano is placed below the frame 1, and the flexible array pressure sensor is laid on top of the roll-up piano. When a key in the piano key assembly 2 is pressed, the corresponding first pressure rod 212 and second pressure rod 221 will press on the key of the roll-up piano, and the roll-up piano will produce sound.
[0042] Specifically, the controller 3 is also equipped with a display screen. The display screen is used to display the evaluation score.
